# Mock Loggers



Different logging services can be tested using mock loggers backed by [Mockito][].



> [!WARNING]

> This library does not support _parallel test execution_.

## How to use



The simplest usage example looks like this:

```java

@Test

void helloWorld() {

    var helloService = new HelloService();



    assertDoesNotThrow(helloService::sayHelloWorld);



    verify(System.getLogger("HelloService")).log(Level.INFO, "Hello World!");

}

```



Now this library implements services for [JDK Platform Logging][jdk-logging],

[Apache Commons Logging][commons-logging] and [SLF4J][slf4j].



See more examples in the relevant modules of this project:



- for Apache Commons Logging in [mock-loggers-commons-logging](commons-logging)

- for JDK Platform Logging in [mock-loggers-jdk-platform-logging](jdk-platform-logging)

- for SLF4J in [mock-loggers-slf4j](slf4j)



## Other logging libraries and frameworks



- [Apache Log4j: Unit Testing in Maven][log4j-unit-testing-in-maven]

- [Unit Test logback Using JUnit][logback-unit-test-using-junit], it's old but gold



## Credits



There are two projects which inspired me to make this library:



- [s4u/slf4j-mock][slf4j-mock]

- [ocarlsen/mock-slf4j-impl][mock-slf4j-impl]
